JETTY.

. Application filed March 20, 1923. Serial No. 626,342.

To all whom t may concern.'

Be it known that l, HENRY Fnnniucu. KnLLNnu, a citizen of the United States, and a. resident of Silver Lake, in the county of Shawnee and State oi Kansas, have invented certain new and useful linproveinents in Jetties, ot which the following is a specilication.

rl"his invention relates to jetties and has for its object the provision oi' a device which will eiiectually prevent the erosion ot river banks and inaintain the river along' a predeterinined course in its natural bed.

further object of the invention is the provision oi5 a device adapted to be applied to river bank for preventing' deterioration ot said bank and which may be simply and cheaply constructed while at the saine tiine being etlective for the purpose.

Another object ot the invention is the provision of a plurality ot devices adapted to be anchored in spaced relation along a river bank which is in the process ot erosion by the swiftly moving waters, with the devices F being arranged at an angle of o to the direction of flow of the water and strung` out iu the direction of the current.

still further object of the invention is the provision oi' a plurality of devices adapted to be anchored in spaced relation along` a river bank to pre-vent the erosion of said bank and which are connected together by a flexible ineans with the devicesl being arranged at an angle to the direction of flow of the water and extended towards the direction of flow.

@ther objects and advantages will becoine apparent during the course ot the following description.

The invention is illustrated by way of enainple in the accompanying drawings, in which,

Figure l is a longitudinal side view oit a plurality c'ii sections on the jetty with each section triangular in cross section.

Figure 2 is a view in perspective ot the section ot the jetty shown in Figure l.

Referring to the drawings, l designates a river bank which is in the process ot erosion due to the swiftly moving` waters or" a river. ln order to prevent such erosion or deterioration of the bank it is necessary to provide seine ineans, preferably ot a skeleton structure, which will permit the water topass through the saine but will nevertheless check the current at this point and tend to niaintain the curre-nt more directly in the center ot the bed of the stream and away frein the banks which are atlected by the running water.

The sections or' the jetty are triangular in cross section and are built up oi three triangular endless bands 22. Each oit the bands 22 is composed of three angle irons 23 provided with a plurality ot pertorations 24 spaced at least two feet apart and through which are passed flexible strands 25. The three bands are rigidly connected together by n'ieans oit' three angle irons 26 which are substantially sixteen 'feet long. These angle irons niay be bolted or riveted tothe end and intermediate bands 22 as inay be desired. rlf'he bars 23 of the end bands are connected together by ineans ot the angle irons 26.

rlhe cables 25 passing through the perforation at the extreme end of the triangular bands 22 are extended to a point on the bank which is secured to the post or deadinan 11. rihe cables 25 are extended troni the inner end of the triangular section as shown at 25h and pass through perforations on the inner end et a second triangular section of the jetty. As many triangular sections may be added to the cables to forni the jetty as desired. The cables 25b are substantially 8 feet long or one half the length of the triangular vsection. The cables 25a are secured in any approved rnanner to a dead man 1l located on the bank l.

Jetties constructed in accordance with iny invention are adapted to protect a river bank to prevent erosion by the diversion of the current and is also adapted to provide for silt accumulations. rllhe spacingv of the cables is suiiicient to perinit the water to pass readily through and deposit the silt or inud upon the lower side ot the jetty and the weight of the trainee is sutiicient to cause said 'trainee to sink readily without the necessity ot requiring` added weight whereby the inner tree end oi the jetty will be lowered sufficiently below the navigation line to permit ships to pass and it is further noted that no sharp projections appear upon any portions of the conipleted jetty which will in any way interfere with the navigation oi' the streain. rlhe jetties inay be inade ot any length, but l prefer to construct thein at least troni eighty to one hundred feet.

While l have disclosed the sections as constructed of angle irons, l wish it to be llf) down strezun.

understood that any kind or Aforni of inni@ rial may he employed without departing from the scope ot the invention.

The simplicity 'of the construction furnishes a jetty which muy be cheaply inede Without ull'ecting the usefulness and :turtl'iei more the saine may he shipped to its point ot' destination unasseinhled in smell bundles and readily set up at the river barili.

The completely constructed jetties :ire placed at least 'titty ieet spart along e river bank which is in the process of erosion and located at an angle 0lE substantially 450 'to the direction of vflow o'lf the current and rlhe flexible ehles muy be inadeofwire or any other materiel suitable for the purpose.

vWhat I cluiin is:

A jetty composed oft a plurality of frames,

each ot said trainee composed o'l' e peir ci spaced perforated triangular lnetsl hands o angle iron construction and an intermediate triangular band of siini'lar construction.` spaced angle iron bars rigidly connected to the triangular bands und spaced at 1200 spurt, a plurality of spaced liexible strands inserted through the perioretions in the metal bands, and extended beyond the ends of the frames and having` other spaced trainee connected together hy said 'flexible strands, with the strands passing through perforations in cachot the .triangular shaped hands of the frames so that the jetty Will he composed of spaced rigid vfrances conH nected together by a plurality ol' idexible strands arranged in triangular formation.
